The Bazoş estate was acquired in 1867 by Barons István Ambrózy and Lajos Ambrózy, while the dendrological park in Bazoșu Nou was later developed by Count Lajos Ambrózy, who served as the Austro-Hungarian Empire's ambassador to the United States.[1] Between 1909 and 1914, under the guidance of German landscaper Franz von Engerhord, director of the Düsseldorf Botanical Garden, a portion of the 150-year-old natural oak forest on the family estate was transformed into a landscaped area and enriched with dozens of plant species imported from America, particularly from the Harvard University arboretum.[2]
While the park was being developed, a castle was also constructed. The castle, which featured 100 rooms, served as Ambrózy's vacation residence.[3] Following the end of World War I and the dissolution of the Austro-Hungarian Empire, Count Ambrózy was expropriated through agrarian reform, and the park's land was transferred to the Romanian state. According to one account, an enraged Ambrózy ordered the castle's demolition and distributed the bricks among the residents of Bazoșu Nou.[4] Another version suggests that he sold the castle and permanently relocated to Vienna. In 1934, the new owners allegedly demolished the building and sold the bricks to settlers arriving from Transylvania.[4] The only remaining structure from the original estate is the castle's water tower.[5]
In 1934, the park was acquired by the State Forest House and assigned to the Institute of Forest Research and Management. It was designated a scientific reserve in 1954, and in 1982, it was officially declared a natural monument.[6]
